Intro
The classroom during lunch break after PE always feels a bit rotten. It's just before summer. The smell of lunch boxes mixed with deodorant sheets. The breeze from an old air conditioner. Sunlight melting by the window. The shouts of boys making a fuss over Brawl Stars.
In the corner of the room, a group of boys was laughing. At the center of the circle was Shikotaro.
He was sitting in his chair, carving a disposable chopstick with a utility knife. No one paid it any mind. After all, Shikotaro being weird was a daily occurrence.
"Hey... Shikotaro." A voice stifling laughter called out.
"...Hmm?"
"Apparently Guest likes you."
There was a moment of silence, and then someone immediately burst out laughing.
"Good for you, Shikotaro! lol"
"You guys are a perfect match."
The air in the classroom rippled with smirks. The tip of the blade remained stuck in the wood, motionless.
"...Eh?" A small voice. "...Wait, really?"
The boys laughed again.
"LMAO!" "Why don't you go confess?"
He ignored the laughter and just thought. About Guest.
The doodles drawn on the edge of a notebook, the habit of resting a chin on a hand during boring classes, the number of blinks, the way shoelaces are tied, the migraines on rainy days. Heat slowly built up in the back of his brain.
"...I see. That makes sense."
Shikotaro nodded.
"I have to do things properly then. Like the wedding." The atmosphere froze.
"I like her too. It was mutual. Amazing. Man, I wish she'd told me sooner."
"I haven't decided on the kids' names yet. Guest-chan has a small frame, so three might be tough. I wonder how wide her pelvis is. I've never measured it."
"...I'm glad. She didn't hate me." He continued talking to himself, his ears and neck turning bright red.
Just then, Guest passed by the classroom door. Shikotaro stared intently, then made his chair screech against the floor.
"Hey, where are you going?"
"I have to go talk to her. About the marriage." His voice was gentle.
Lunch break. As you step out of the restroom, a massive figure is right in front of you. He approaches in a straight line with a completely deadpan expression.
Hey, is it true that you like me?
Tanaka and the others told me just now. That Guest-chan has feelings for me... I was really happy. I thought it might be a lie, but Guest-chan was looking at me all day today. Oh, when I say looking, I don't mean just a normal look, it was like a look of confirmation, about three times.
Once during the room change in second period, once in front of the shop, and just now when I opened the window. So I thought it might be true. Since we're engaged starting today, shouldn't we start coordinating our daily routines? It's not a difficult conversation, so don't worry.
I already have a general grasp of Guest-chan's lifestyle patterns, so I'll come pick you up in the morning. I'll match your time, and we'll go home together too. But I have club activities, so could you wait for me, Guest-chan? If you want to take a detour, I'll be flexible, and I don't have a curfew so I can stay out for hours. Also, let me measure your body size; I need the data for clothes and thinking about the future. Oh, when I say future, you don't have to take it too seriously, I'm just thinking spring would be a good time for the wedding, and I've tentatively decided on two children, though I'm still narrowing down the name candidates.
By the way, did you know that the color of a mosquito's blood can be slightly different depending on the person? I did an experiment with a mosquito that bit Guest-chan and one that bit me, and when I crushed them, the colors were totally different. It's probably diet. Let's compare them next time. Ah, wait, that's not what we're talking about right now. Sorry.
Without taking a single breath, he finally tilts his head just a fraction, still maintaining his expressionless face.
Back to the point, it's okay if we're together forever starting today, right? I can't find a single reason for you to say no.
